Page 10: Checking The Heater
Checking the heater If defrost system failure，check the heater and the temperature fuse as well as wires. Measuring temperature fuse and heater resistance about 304Ω then it is OK.( gray and Blue) Checking the defrost fuse Fuse is a high temperature protector of defrost system, when defrosting, if it feel the temperature is more than 73℃, it will cut off the defrost heater, stopping defrost, so that it can protect the parts. -

Using a multimeter with the ohm switch to measure the resistor of sensor, normally at surrounding 25℃ the resistor should be about 2kohm and every with the temperature decreases 1℃ the corresponding resistor value would increase about 45ohm. If the measured value is not within the normal scope, the sensor is bad and needs to repair or change. -
